Present Perfect Simple Tense

We form it with HAVE (I, you, we, they) / HAS (he, she, it) and past participle.

Regular past participles have the -ed ending (watched, played, visited), while irregular past participles must be learnt by heart (3rd column of the list).

Take a look at these examples:

Lucy has painted her house blue. --> She's painted her house blue.

Jimmy has written a letter. --> He's written a letter.

Do we know when these actions happened? - No, we don't. 

Is it important? - No, it isn't.

What happens in the negative sentences?

I have not ridden a camel. --> I haven't ridden a camel.

She has not seen a ghost. --> She hasn't seen a ghost.

And questions?

Have you finished your homework?

What have you done?

Why do we need the present perfect simple?

• to connect the past and present:

        I've heard that song before.

• when the result is more important than when something happened:

        She's cut her finger.

Common time markers are: ever, never, already, yet, since (2002), for (3 years), just
